AUTOMATIC CORKSCR-EW.

Application filed August 11, 1921.

T 0 all whom it may concern:

Be it known that I, JOHN CHMURA, citizen of United States, residing at Marmarth. in the COUHty of Slope and State of North Dakota, have invented certain new and use ful Improvements in Automatic Corkscrews, of which the following is a specification.

One object of this invention is to provide a safe, practical. efiicient, and rapid device for removing corks from bottles.

Another object of this invention is the means by which the screw or gimlet is withdrawn into the frame permitting handling without danger to the fingers.

A third object is the provision of means for greatly assisting by spring action the removal of a cork.

These and other objects are attained by the novel arrangement and construction of parts described in the specification and shown by the accompanying drawing forming a material part of this disclosure and in which Fig. 1 is a partial sectional, partial elevational view of the device in position for pulling a cork.

Fig. 2 is a sectional view showing the puller head in position before entering the gimlet.

Fig. 3 is a similar view showing the ejector spring partially compressed and cork started upwards.

Fig. 4 is an elevational view of the operating handle and compensating spring projecting.

Referring to the figures in detail. the numeral 10 designates a bottle having a neck terminating in a thickened wall forming a mouth adapted to receive a cork 11.

An annular metal body comprising a hub 12, and a concentric cup shaped lower portion 14 encloses an open wound ejector spring 15, one end being secured to the bottom of cup while the opposite end is attached to a disc 16, acting as an ejector plate and is provided with a central opening through which the cork can pass when being withdrawn. Near the outer edge, interiorly of the cup, is a bead or ring 17, preventing I the disc 16 from being forced by the spring 15 out of the cup 14.

Specification of Letters Eatent.

Patented June 27, 1922.

Serial No. 491,354.

lVithin an annular opening formed centrally through the hub 12 is a short rod 18 to one end of which is secured a tapered spirally twisted pointed element forming a gimlet 20, adapted to pierce the cork 11, rotary penetration being produced by means of a spiral groove 21, formed on the rod 18 and a screw 22 having a pilot engaging the groove.

By referring to Figure 2 it will be seen that the groove 21 does not extend the full length of the rod. solid ends being left preventing the rod from displacement.

A compression spring 24, enclosed within an opening in the handle 25 secured to the hub 12, urges the rod and gimlet downward.

In operation the device is placed against the mouth of a corked bottle and pressure applied to the handle forces the disc and spring 15 upward into compression and further advances the ginilet into the cork.

Conversely releasing the pressure on the handle, the tension of spring 15, supplemented by a slight initial up pull of the handle withdraws the cork from the bottle.

From the foregoing it will be seen that a neat appearing and efficient implement for the purposes set forth has been disclosed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In a semiautomatic cork-screw comprising a handle, an axially stemmed cylindrical cup secured adjacent the handle. said handle having an annular recess axially of the handle and cup stem. a spring in said recess, a spirally grooved rod operable in the recess against the pressure of said spring, a pointed spiral adapted to enter a cork fixed in the lower end of said rod, a disc within the cup for supporting the structure. said structure being rotatable about the bottle neck, a

spring interposed between said disc and said cup, and a flange extending in from the lower edge of said cup. said flange maintaining said disc within the cup and also be ing adapted to direct liquids downwardly and against the wall of the bottle.

In witness whereof I affix my signature.

JOHN OHMURA.
